Swift was announced by Apple in June at its WWDC developer conference, making it less than a year old. The prominence of the language and huge developer interest indicates it’ll continue to be popular in 2015 and should eventually surpass Objective-C (which is likely what Apple always intended).

Javascript took first place as most popular language on Github, thanks to its widespread use on the internet. It only just inched out Java this time around, however.

The rankings are made by analyzing language discussion on Stack Overflow and actual usage on Github in order to get an idea of which languages are growing in popularity and which are shrinking.
